Test a Prime Wheeljack head or BH Wheeljack head in that bot. I sent XSilverboltX a Wheeljack head to base it off of.
Depends... does TFA Rodimus have a head that sits on a ball joint, or is the ball joint the one that fits in the torso?
If I can figure out how to empty the head to make light piping, I promise to make a reversed attachment point.
The first printed head is on its way to me to be tested as to how it fits on RiD Wheeljack. Just waiting on Canada Post.
